Did my first batch of cheapo amiibo cards
Laserjet compatible business cards and google image search of black and white images.
Just slap the tag on the back and write the amiibo. Nice and cheap. Also not the nicest looking, but do the job well enough.
most are just Smash Bros. but the Kirby Robobot card is the actual kirby amiibo and not the smash one. Both unlock different copy abilities in Kirby Robobot.

DIY amiibo cards... created using blank NTAG215 tags and a little bit of dark magic :)

You need:
- a blank NTAG215 tag sticker (Shop NFC, AliExpress, ...)
- an amiibo dump (dump your own amiibo, download it, ...)
- a way to decrypt/encrypt amiibo dumps (amiibo decryption service, amiitool, ...)
- NFC reader/writer hardware (USB NFC reader/writer, Android smartphone with NFC, ...)
- compatible software to write an amiibo dump to a blank NTAG215 tag (I could not find any so wrote my own)
- a hex editor (HxD, UltraEdit, ...)
- a picture of the amiibo (download it)
- a printer (printer at home, printer at work, photo kiosk, ...)
- a ruler and a cutter knife

Steps:
- decrypt amiibo dump
- use hex editor to change UID in amiibo dump to UID of blank NTAG215 tag
- encrypt amiibo dump
- write amiibo dump to blank NTAG215 tag
- print amiibo picture and cut it out
- put NTAG215 tag sticker on the back of amiibo picture

hey i was just wondering if maybe you can pass off that program you wrote and maybe help me out on how to write on these nfc tags. i would really appreciate it.
 
Are you looking for Android? You can PM me in that case ;)
i dont know how to pm. ha ha ha :rofl: but i dont currently own an andriod with nfc capabilities. but i do own an action replay nfc reader/ writer. im hoping maybe this piece of hardware.(with the right program) will work. but none the less if maybe you can send me a pm i am interested in looking into the android program. i am going to invest in a better phone soon.
 
hey im trying to extract the file and it keeps saying the file is damaged or a different format. ive tried redownloading it also but no dice. is the zip not compatible with winrar?
Seems like the uploaded file is damaged.

Till they fix the download you can use v1.06 instead

check http://wiki.gbatemp.net/wiki/Amiibo for te memory layout. pay special attention to the encryption status of the pages, while keeping in mind that amiitool will en-/decrypt even the unencrypted parts
 
I have a question... If I already have date on a NFC sticker,can I overwrite it by another character?
